SPRING-TIRE.

Application filed July 13, 1914.

To all whom it may concern Be it known that I, ARTHUR Monson, citizen ofthe United States, residing at Triumph, in the county of La Salle andState of Illinois, have invented certain new and useful Improvements inSpring-Tires, of which the following is a specification.

This invention relates to improvements in spring tires used upon wheelsemployed under automobiles and similar vehicles, and has for one of itsobjects to produce a simply constructed tire construction possessing thesame resilient qualities as the ordinary pneumatic tire without dangerof puncture.

Another object of the invention is to provide a device of this characterwhich may be employed without structural change in connection with theordinary pneumatic tire casings.

\Vith these and Other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claim; and in the drawingsillustrative of the preferred embodiment of the invention Figure 1 is aside elevation partly in section of a wheel and its rim with a tireconstructed in accordance with the invention. Fig. 2 is an enlargedtransverse section on the line 22 of Fig. 1. Fig. 3 is a section on theline 83 of Fig. 2.

The improved device may be applied to the ordinary tire casings employedin con-' ncction with inflatable tubes and commonly known as pneumatictire casings and attached by clencher rims or flanges to the inturnedflanges of the wheel rim, and requires no change in the casing rim orfelly except a plurality of apertures formed through the folly and rimto receive spring supporting clamp bolts. The wheel is shown complete inFig. 1 and comprises the hub portion 10, spokes 11, felly or inner rim12, outer or clencher rim 13 with the tire casing 14 having clencherflanges 15 engaging the inturned flanges of the rim 13 of the wheel,these parts being of the usual construction.

The improvement comprises semi-circular segmental members '16 insertedwithin the casing 14, and preferably formed of sheet metal curved bothtransversely and longitudinally to conform to and adapted to be disposedwithin the casing in the space usually occupied by the expansive tube,and are slightly spaced apart at their confront- Speoification ofLetters Patent.

ing ends. Extending from the telly portion 12 of the wheel and rigidlysupported therein are stop members or rods 17 as shown in 1 whichprevent the members 16 from dlsplacement circumferentially of the wheelwhile leaving them free to be moved in' wardly toward the hub.

At suitable intervals apertures indicated at 18. are formed through thefolly 12 and the rim 13 to receive guide bolts or rods 19. The rods 19are pivoted at their outer ends as indicated at 20 to the members 16 andextend inwardly through the apertures 18 and project for a considerabledistance beyond the inner face of the felly. Surrounding each bolt 19and bearing against the inner face of the felly is a guide plate orwasher 21 which is bolted or otherwise socured to the folly 12. At itsinner end each bolt is threaded to receive a nut 23 and likewiseprovided with a transverse pin 24 near the nut. Surrounding each bolt 19is a spring 25 which is connected at one end to the pin 2 1 and rigidlycoupled at its other end to the washer 21. By this means the spring isarranged to exert a pulling force upon the bolt 19 and force the members16 against the inner face of the casing member 14, and maintaining therotundity of the latter. When no pressure is applied, the pulling forceof the springs is exerted to maintain the casing 1 1 in its outwardlyextended condition, but when pressure is applied to the axle and thewheel depressed, the springs, which for the time being are in downwardposition, are extended by the compression of the casing and produce thesame effect as the ordinary pneumatic tire, and when the pressure isremoved, the reaction of the springs will return the casing to itsnormal position.

Any required number of springs may be employed, but will generallycorrespond to the number of spokes, one of the spring supported boltsbeing located between adjacent spokes as illustrated in Fig. 1, but itis not desired to limit the number of bolts employed, as they may beincreased or decreased in number as required.

The improved device is simple in construction, can be inexpensivelyapplied, produces .an efiicient, resilient wheel which possesses all ofthe advantages of a pneumatic tired wheel without danger of puncturedeterioration.

The apertures 18 are in.elongated form to prevent the cramping of theparts '19 When the load is applied to the axle. A hood 26 ispreferablyarranged over each of the inwardly projecting rods 19vand itsspring, as shown, to protect the same. Each of these hoods 26 is in thenature of a metal cap open at one end and provided With oppositelydisposed radial ears it being observed that the said hoods are mountedWith the ears thereof seating upon the Washers 21 to be secured theretoin any suitable manner, as illustrated in the drawing. Having thusdescribed the invention, what is claimed as new is: V

i A Wheel including a felly having a hollow tire mounted thereon,semi-circular segments fitting Within the tire, a plurality of guidemembers swingingly connected to each of said segments and projectingfreely through the folly, yieldable means engaging the inner ends ofsaid rods for urging the segments radially of the felly, and oppositelydisposed radial stop rods secured to the felly upon opposite sidesthereof and projecting between the confronting ends of said segments.

In testimony whereof I affix my signature in presence of two Witnesses.
